GEGRGE M. STONE AND GEORGE VI. CUYLER, OF CEDAR RAPIDS, IOWA LOCOMOTI'VEJOURNAL BOX Application filed February 9, 1928. Serial No. 253,091.

This invention relates to a locomotive journal box, one of the objectsbeing to provide a brass which can be removed without the necessity oftaking the driving box ofi of the '5 axle.

Another object is to provide a device of this character in which thebrass is mounted for rotation within the box, simple and efficient meansbein provided whereby the working parts can e properly lubricated.

Another object is to provide a floating bushing which requires noadjustment after being put in place and necessitates only a slightmodification of the journal boxes now in use.

A. still further object is to provide a bushing applicable to all kindsof axles.

Another object is to provide a-sectional bushing mounted for rotation inan eccentric wear member, the parts of the bushing being of such lengthas to be removable readily through the opening in which the cellar ofthe box is removably mounted.

lVith the foregoing and other objects in 'view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings,

Figure l is a side elevation of a box having the present improvementscombined therewith.

Figure 2 is a view partly in top plan and partly in horizontal sectionthrough the structure disclosed in Figure 1.

Figure 3 is a section on line 3T3,'Figure 2. Figure 4 is a section online 4 1, F lgure 1.

Figure 5 is an enlarged section through a portion of the structure takenon line 55, Figure 4.

Figure 6 is an enlarged section on line 6-6, Figure Referring to thefigures by characters of reference 1 designates a driving box pro videdwith a cellar 2having a removable end plate 3. An eccentric bushing 4,preterably of steel, is fitted snugly in the box 1 and held in positionby anchor screws 5 one of which is shown in detail in Figure 6. Thebushing e terminates flush with opposed Walls of the opening 6 in whichthe collar 2 is mounted and arranged across this opening spring 12 isinterposed between the stiffening plate and the bottom of the cellar,this spring being located between a pair of indicatorpins 1.3 which areattached to the stiffening plate and are slidablc within openings 14 inthe bottom of the cellar. formed in the bushing 7 as indicated by dottedlines in Figure 4 so that a lubricant can thus pass through the bushing7 from agrease cake G held between the follower plate 8 and the bushing7. Obviously this cake is constantly pressed against the bushing 7 bythe spring 12. The cellar 2 is held reinoyably in position by anysuitable means such as cross pins 16 extending transversely therethroughand through ears 17 extending from the box 1.

Mounted for rotation in the space surrounded by the bushings i and '7 isa floating brass 18 which, as shown in the drawings, is

formed of three sections placed end to end and of the same length. Thelength of each section is slightly less than the width of the opening inwhich the cellar 2 is mounted so that, by removing the cellar thesections can be successively removed from or placed in position withinthe box. In the structure illustrated the sections of the box have theirends radially disposed but it is to be understood that these ends can bearranged at any desired angles. All of the sections of the brass areperforated as at 19, thereby to permit the passage of grease to themember j our- Apertures 15 are nalled in the box. A perforated flangemay be located at one end of each of the sections of the brass so thatwhen the sections are assembled these flanges will form a continuousannular flange. Apertures 21 are extended through the flanges and areadapted during the rotation of the brass, to move into and out ofregister with corresponding apertures 22 formed in one end wall of theremovable cellar.

Importance is attached to the fact that the sections of the brass can beplaced in and removed from position without first removing the wheels orrenewing the whole bearing. Furthermore it is possible with thisstructure to utilize the designs of boxes already in use. In order torenew the brass it is merely necessary to jack up the box after whichthe sections of the brass can readily be inserted and slid into ositionor vice versa. The practice hereto ore has been to press a half of abrass into the box with about fifty tons pressure so as to cause thebrass to hold fixedly in the box. It has been found, however, that thebrass constantly works loose, thereby creating a defect which must betaken care 0 In the present structure, however, the floating brass has aneat but rotating fit and the openings therein provide a means wherebygrease can be supplied constantly to all parts of the bearin surfaces.While the structure is designed ihr use in driving boxes, it can also beemployed to advantage on trucks of all kinds of locomotives.

W hat is claimed is:

The combination with a box having an opening, a cellar removably mountedin the openin and a spring pressed follower in the cellar ibr supportinga lubricant, of a sectional brass mounted for rotation in the box andhaving apertures for receiving lubricant from the cellar, the sectionsof the brass being removable separately through the opening after theremoval of the cellar, and apertured flanges carried by the sections atone end cooperating to provide a continuous annular flange outside ofthe box, there being apertures in the cellar for supplying lubricant tothe apertures in the flanges.

In testimony that we claim the foregoing as our own, we have heretoafiixed our signatures.

GEORGE M. STONE, GEORGE W. CUYLER.
